(Thermochemistry)
create two solutions such that when you mix equal amounts together, the resulting solution has an initial temperature of 50 degrees Celcius. Note that each flask contains 100 mL of solution. we can assume the heat capacity of the aqueous solutions is equal to 4.18 J/gK degrees.

Butterfly wingspan is 7.7

Ithink that’s it’s b

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.

Pretty sure it's d. heterogeneous is separated by physical properties.
